"""About this script:-
This script enables the fast creation of multiple loops on a mesh.

Usage:-
1)Click the FastLoop button on the Tool Shelf to activate the tool. 
2)Hover over the mesh in the general area where you would like a loop to be added (shown by a highlight on the mesh).
3)Click once to confirm the loop placement
4)place the loop and then slide to fine tune its position.
5)Repeat 1-4 if needed
